Victory: 1999-09 Victory all models Yamaha: 2008-09 Raider2002-09 Road Warrior/ 2006-09 Roadliner, Stratoliner/ 2002 TDM 900/ 200709 V-Star 1300 This product is a great fit for stock bikes with exhaust and intake mods. It is also capable of handling the fuel needs of big bore kits, light cams, and a variety of head porting. This is an Electronic Jet Kit. Like jet kits in the past, the more you modify, the more responsibility you take in getting your fuel curve right. Going to www.dobeckperformance.com will help you obtain better high horsepower tuning.
Note: If your model is equipped with a 02 sensor in the exhaust, you will need to disable it or leave the first dial (green) at the 1:00 oclock position. Any questions call tech support.
Due to the complexity of the newer motorcycles, dealer install may be required. If you have any questions about this installation please call tech support.

INSTALLATION (For any and all help during install or tuning please call us(8-5M.T. m-f), we cant help if you dont call) 1. Before installing the TFI you must first disconnect the negative lead from the battery. 2. Determine a location for the TFI box, we recommend under seat, or behind a side cover. 3. Locate a switched power lead. We recommend taillight power source. All other power sources MUST be carefully considered to avoid any damage to bike or TFI. Locate the power wire and attach T-tap to the lead as described on the recommended settings page. Cut the red wire (TFI) to length, slide insulator onto red wire (TFI) then crimp the spade connector onto red wire (TFI). Now connect the red wire (TFI) to the T-tap. Our information covers the most common applications. If your bike does not appear try our web site for additional applications or try calling tech support. 4. Locate ECU. In the ECU harness, locate the injector wires as described in the illustrations on the recommended settings page, then attach T-taps to those leads. Connect the blue and gray leads (TFI) to the T-taps using insulators and spades as before. It does not matter which order the blue or gray leads attach to the injector leads as long as they are the leads described on the recommended settings page. 5. Locate grounding point. We recommend the negative side of the battery, or a common grounding lug, that the stock wire harness is using. Crimp the ring terminal supplied with the TFI to the black wire (TFI). You may cut a section of the ring out, allowing the terminal to slide around the bolt without removing it. 6. Be sure to check the wires are not in direct contact with any sharp edges, exhaust and/or other objects, which could result in long term wear and/or damage. 7. Connect the TFI ground lead to the negative terminal of the battery along with the factory ground lead. 8. Turn the key on and check for a flashing green LED. If yes, go to step 9. If you have no flashing green LED, re-check/confirm connections then retry and/or call tech support. 9. Start the motorcycle. The TFI is programmed not to add fuel at idle. This may cause the LEDs to flash at idle, this is normal. Some models may have a solid green LED at idle, this is also normal. If the green or red LED is flashing by itself (See troubleshooting TFI).

Electronic Jet Kit Instructions Tuning
(For any and all help during install or tuning please call us(8-5M.T. m-f), we cant help if you dont call) Green LED pot(1st): Air fuel mixture screw adjustment. With TFI installed and the bike fully warmed up, screwdriver in hand, locate the green LED and the pot right below it. Using the throttle raise the RPM to a high idle or about 2000-RPM. Once there, slowly turn the green pot clockwise from the 1:00 position (off) until you achieve the highest RPM and smoothest running sound (like a mixture screw on a carburetor). You should find the best setting between 2:30 and 4:00 oclock. If you turn the green pot clockwise and the engine does not accept any more fuel (RPM drops when adding fuel) you may have one or more of these problems (See troubleshooting Motorcycle). Yellow LED pot(2nd): Acceleration fuel adjustment (bottom to mid range fuel). Anytime the yellow LED is on, this pot is adding fuel. In neutral raise the RPM slowly up through the mid range and see no yellow LED. However, opening the throttle quickly from idle you should see the yellow LED come on. Fine tuning: Start with the suggested setting and then add clock position at a time until the bike says too much (hesitation) then back off 1 clock position, if worse go opposite direction. If no yellow LED there is not enough load to turn it on. At that point the street or dyno will be able to show the difference. The yellow pot adds its fuel below 70% of maximum RPM. Red LED pot(3rd): Main jet fuel adjustment (top end fuel). It adds about 2.5 points of main jet fuel with every clock position. For example, one clock position is the same as 150 to 152.5 main jets. Fine tuning: Start with the suggested setting and then add clock position at a time until the bike says too much (hesitation) then back off 1 clock position, if worse go opposite direction. The red pot adds its fuel above 70% of maximum RPM. RPM pot(4th): All V-twins. Sets the RPM that the red pot fuel (main jet fuel) turns on. One clock position is roughly 1000 RPM. This pot should be set to about 70% of redline. (For example: Suzuki M109R redlines at 5800 RPM and 4000 is roughly 70% of redline which would be 4:00 oclock). Some dual plug systems (Kawasaki, Suzuki) need to double the RPM clock position to have the same results. Verify setting by raising the RPM in neutral, look for green and yellow LED to shut off and the red LED to turn on at the chosen RPM or refer to suggested settings if you have no tachometer.

Troubleshooting

(For any and all help during install or tuning please call us (8-5 M.T. M-F), we cant help if you dont call) TFI When the green LED is flashing by itself there is an incomplete connection with the injector lead (motorcycle) and blue lead (TFI). If the red LED is flashing by itself there is an incomplete connection with the injector lead (motorcycle) and gray lead (TFI). Confirm the injector leads as shown in the illustrations on the suggested settings page and the T-taps/connections are firmly in place and secure. Motorcycle (Order from most common to least common) 1. Engine not fully warmed up. 2. A vacuum leak on the intake. 3. High lift cams affecting map at light loads and low RPM. 4. Cylinder head temp sensor malfunction. 5. The loss of TPS and ECU sync.

POOR MILEAGE Solution: 1. Check your green pot setting. This setting is generally responsible for 90% of your mileage. In the hundreds of installs performed, we have never gone beyond the 4:00 setting. Try backing down the green setting slightly. You can slightly lower the yellow and red settings also. 2. RPM pot adjusted too low**. Make sure the red LED is turning on no lower than 70-75% of the maximum rpm. 3. Make sure your engine passes the 2000-RPM test at the beginning of the troubleshooting chapter. If you still have mileage issues call tech support at 877-764-3337 **: Some engine setups can dictate a higher or lower setting on the RPM pot.
